It is very easy to use,it has all tools you need for your business in one place so that there's no searching around or confusion while trying figure out how something works when it comes time to set up an invoice! I wish we could add more services but this was perfect as far as what our needs were at first glance!! No issues with workablenzone other than maybe their support team can do better? This software makes setting invoices super simple - just drop everything into my inbox within seconds of creating them by emailing me directly from inside WZ rather then having 2 separate systems (WL & Z).
